Detailed description of the invention
With specific embodiment, the inventive method is described in detail below.
Certain 380V wire pole tower iron hoop rusty stain processing method, step is as follows:
(1) the rusty stain situation on shaft tower iron hoop surface is carried out semi-quantitative analysis, determine the quality of rusty stain；
Using corrosion calibrator to measure shaft tower iron hoop rust thickness, to obtain maximum corrosion depth be 0.001cm, it is judged that iron hoop corrosion degree is mild corrosion.Meanwhile, measure a diameter of 21cm of shaft tower, the width of iron hoop is 5 cm, iron hoop ear length 4 cm；The area of estimation rusty stain part is: (3.14 × 21+2 × 4) × 5=369.7cm3: according to rusty stain thickness and the quantity of area reckoning corrosion product: 5.24g/cm3× 0.001 × 369.7=1.94(g)
(note: rust density is about 5.24g/cm3).
(2) determine according to the quality of rusty stain and remove the actual amount of the liquid cleaner needed for rusty stain；
React according to rust soluble chemistry: Fe2O3+6HCl=2FeCl3+3H2O, dissolves 1.94g ferrum oxide and needs hydrochloric acid 2.66g hydrochloric acid；
By calculating, when using ML-05 type salt acid cleaner (hydrochloric acid mass concentration 5%, IS-156 type restrainer mass concentration 0.2%), need abluent 53.2mL in theory.Studying and repeatedly practice have shown that: under normal circumstances, the abluent consumption of the rusty stain cleaning completing shaft tower surface is about 2～3 times of theoretical amount, and therefore taking safety coefficient is 3, then this cleaning needs abluent 159.6 mL(53.2 × 3).
(3) use liquid cleaner, carry out decomposing around moistening and thawing to shaft tower rusty stain by the method for spraying so that it is separate with shaft tower surface, come off, until exposing shaft tower and iron hoop matrix；
Measure about 160 mL
ML-05 type salt acid cleaner, be loaded in hand-holdable squash type spray bottle, twist good bottle cap, check sprayer unit intact；Every safety measure of livewire work is carried out according to electric power safety regulation；Step on tower and carry out chemical cleaning project: abluent is sprayed onto uniformly, slowly on corrosion product and attachment matrix thereof, spraying time general control was about 30 minutes (can not be the fastest), spray and spray 5 times the most continuously, position serious to uneven place or corrosion can suitably escalated dose or spraying number of times, consumption, it is ensured that rusty stain can preferably come off, remove；Must note in the process keeping health and the alive circuit of workmen safe distance, forbid by cleanout fluid splash to any metal materials such as alive circuit, forbid to stand below construction operation region people.The working standard sprayed is: rusty stain is substantially all to come off or melts, and exists without obvious rusty stain.
